He should be dealt with appropriately - a life ban and imprisonment are not the answers. Imprisonment should be to protect the public, not to punish. As he is grounded (and should be for 5 years or so in my humble opinion) the public are protected.

After that, a compulsory course on alchohol abuse might be in order.
